−13° on Nov. 12, 1966, the coldest reading for this week of the year since 1951. Next is −10° in 1959.
Solon Springs’s center stands about 1,110 ft above sea level. Within three miles the land runs from 1,010 ft to 1,300 ft, a difference of 290 ft: rolling country. The highest named summit within 15 miles is Pikes Peak, about 1,330 ft, 10 miles northwest.
Under the town center the state geologic map shows Copper Harbor Conglomerate (sandstone, conglomerate), from the Mesoproterozoic, 1 to 1.6 billion years old.
The section below crosses 2 rock units mapped at the surface.

Sandstone, conglomerate. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 14 mi of the line.
Basalt. Age: Mesoproterozoic, 1 to 1.6 billion years old. About 10 mi of the line.

A raindrop that lands in Solon Springs reaches the Gulf of America by way of the Saint Croix and the Mississippi: about 1,960 river miles.
Lakes on the way: Lake Pepin and Lake Mallalieu 175.
